lol at the conversation in here...
i, very unseriously, voted no as i'm wearing a nismo jacket as we speak/type and i don't have any nismo parts, let alone a car!
but seriously, if it's on the car, it implies that you have the part. with the general definition of rice being a modification to make your car look fast, as apposed from make it look good, a nismo sticker on the car is implying the false sense that it's fast.
fake stickers = the definition of rice
edit: nismo is probably a bad example of a 'fake' sticker, as nismo = nissan motorsport int.... a stock nissan can still go round a track. like a holden gts with a hsv sticker. replace nismo with apexi or hks or soemthing
